exclusive terms I have described, does certainly seem, and for years did seem to myself, little short of insanity. Of this I am sure that no student of Kant, having the passage before him, can have known heretofore what consistent, what rational interpretation to give it; and, in candour, he ought to own himself my debtor for the light he will now receive. Yet, so easy is it to imagine, after a meaning is once pointed out, and the station given from which it shows itself _as_ the meaning--so easy, under these circumstances, is it to imagine that one has, or that one could have, found it for one's self--that I have little expectation of reaping much gratitude for my explanation. I say this, not as of much importance one way or the other in a single case of the kind, but because a general consideration of this nature has sometimes operated to make me more indifferent or careless as to the publication of commentaries on difficult systems, when I had found myself able to throw much light on the difficulties. The very success with which I should have accomplished the task--the perfect removal of the obstacles in the student's path--were the very grounds of my assurance-that the service would be little valued. For I have found what it was occasionally, in conversation, to be too luminous--to have explained, for instance, too clearly a dark place in Ricardo. In such a case, I have known a man of the very greatest powers, mistake the intellectual effort he had put forth to apprehend my elucidation, and to meet it half way, for his own unassisted conquest over the difficulties; and, within an hour or two after, I have had, perhaps, to stand, as an attack upon myself, arguments entirely and recently furnished by myself. No case is more possible: even to apprehend a complex explanation, a man cannot be passive; he must exert considerable energy of mind; and, in the fresh consciousness of this energy, it is the most natural mistake in the world for him to feel the argument which he has, by considerable effort, appropriated to be an argument which he has originated. Kant is the most unhappy champion of his own doctrines, the most infelicitous expounder of his own meaning, that has ever existed. Neither has any other commentator succeeded in throwing a moonlight radiance upon his philosophy. Yet certain I am, that, were I, or any man, to disperse all his darkness, exactly in that proportion in which we did so--exactly in the proportion in which we smoothed all hindrances--exactly in that proportion would it cease to be known or felt that there had ever been any hindrances to be smoothed. This, however, is digression, to which I have been tempted by the interesting nature of the grievance. In a jesting way, this grievance is obliquely noticed in the celebrated couplet-- 'Had you seen but these roads before they were made, You'd lift up your hands and bless Marshal Wade.'
